IMPROVEMENT IN TILE-MACHINES. g

Speciiication forming part of Letters Patent No. 116,480, dated J une27, 187

To l@all whom it may concern:

Be it known that I, ZENO F. PARUS, of the city and county of Baltimore,in the State of Maryland, have invented certain new and useful-Improvements in Machinery for the Manufacture of Drain-Tiles; and I dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawingthrough letters of reference marked Figure 1 represents a side elevationof a tilemachine with one portion shown in section. Fig. 2 shows a planand cross-section of the same por- -tion on an enlarged scale.

In the ordinary manner of manufacturing pipetiles the bell-mouth orfemale end of the pipe has been formed by spinning the plastic tube, orby the attachment of such bell-mouth, separately formed, before-burning.The object of my invention is to manufacture the pipe with a male andfemale end at one operation and it consists in a novel construction ofdie, in which the female end of such pipe is formed; furthermore, in anovel construction of the disk or block on which the interior of saidend is formed; and in the application of a supportvto such disk or blockin such manner as to be unyielding while the bellmouth is being formed,and to drop into a recess in the platform instantly on release of thelevers by which it is supported, leaving a level surface for the truckto be run off when the desired lengthof pipe is formed.

Referring to the accompanying drawing, A represents the framing tosupport the several parts of my apparatus, in the upper part of whichthe compression-cylinder B is rigidly seated. Within this cylinder isarranged a piston or other suitable device for compacting the clay andforming the pipe as in other pipe-tile machines, said piston beingoperated by gearing R and screw S, arrangedabove it. Beneath the mouthof the cylinder B a platform, C, is suspended by cords D passing overpulleys e, and counterbalanced by weights f. This platform carries atruck, G, having small wheels h, and on which the pipe, when formed andsevered from the clay in the cylinder above, may be conveyed to aconvenient position to be removed from the matrix H. The matrix Hconstitutes the main feature of this invention, inasmuch as in previousattempts to form the bell-mouth or female end of the tube or more parts,constructed in wedge-like form at their connecting lines, in one'or moredirections, so that, pn lifting the pipe, said die will, of its ownweight, drop from the mouth of said pipe. In combination with theplatform C is a disk, l, on the upper end of a vertically-sliding rod,m, which is sustained or supported against the under side of the truckGr by the levers n and o, the

irst of which is provided with a counterbalanceweight, p, by which it isremoved from under the rod m when the latter is released from the toe qof the lever o, and, on release of the said rod, the disk l, at itsupper end, falls into a corresponding recess in the upper side of theplatform C, forming a level surface, and thence descends with saidplarform during the formation of the pipe.

From the above description it will be seen that when all the parts arearranged in the position shown in Fig. l, and the cylinder below thepiston is lled with tempered clay or other plastic material of which thepipe 4or drain-tile is to be formed, the lever o is to be held in theposition shown, to support the dies H and 'i against the mouth of thecylinder until the cavity between said dies is lled with the plasticmaterial from the cylinder B by the pressure of the piston or otherequivalent device thereon, which is indicated by the oozing of suchmaterial through one or more small Oriiices near the lower edge ofthedie i, at which time the lever o should be released, when the platformC, truck G, and die H i will, under a continuance of the pressure on theclay exuding through the annular space around the core-block T, becaused to descend until a pipe of the desired length has been formed,when said pipe is to be severed at the bottom of the cylinder in theusual manner, and the truck G which carries it may run off the platform;after the sectional dies i have been removed the pipe may be liftedbetween tongs or holders of suitable contour, when the die H, from itssectional wedgeshaped construction, will become separated from N EEIOE.

' it, and the pipe is'ready to be placed in the kiln for the purposespeciiied.

2. The die H, made to connect with the coreplug T and matrix i, and madein three or more parts, of Wedge-shape in both length and depth,

so that they Will freely separate from the pipe when the latter islifted from the supportingtable, as set forth. l

3. The disk l, fitting into a recess in the platforni C, in combinationwith its rod mand levers fn and o, for operation, essentially asdescribed.
